Actinopterygii (ray-finned fishes) > Lampriformes
(Velifers, tube-eyes and ribbonfishes) > Trachipteridae
Etymology: Trachipterus: Greek, trachys, -eia, -ys = rough + Greek, pteron = wing, fin (Ref. 45335); altivelis: From the Latin 'altus' meaning high and 'velum' meaning sail - referring to the high doral fin (Ref. 6885). More on author: Kner.
Environment: milieu / climate zone / depth range / distribution range
Marine; pelagic-oceanic; oceanodromous (Ref. 51243); depth range 0 - 900 m (Ref. 36610). Subtropical; 60°N -
Eastern Pacific: Alaska to Chile.

Morphology | Morphometrics
soft rays: 0;
Vertebrae: 90 - 94. First 5 rays of dorsal fin greatly elongated in young becoming reduced with age, otherwise rather higher in center, extending almost to caudal and ends abruptly (Ref. 6885); caudal fin highly asymmetric, dorsal lobe becomes well developed in juveniles with 7-8 rays directed upward at an angle of 45° to body axis, and eventually with growth is much reduced; ventral lobe elongate in young specimens becoming reduced to 5-6 spines directed backward from the caudal base in older individuals; anal fin absent; pectorals small, rounded; pelvic fins elongate in young and juveniles, reduced to base in larger individuals (Ref. 6885). Juveniles iridescent silvery with a series of about 4 dark blotches spaced above lateral line canal; upright and pelvic fins carmine red; larger individuals rather very silvery and greener with light spots, around scales; posterior end of dorsal fin darker (Ref. 6885).
Oceanic (Ref. 2850). Also found near shore, but large adults sometimes feed on the bottom (Ref. 2850). Small individuals feed on copepods, annelid worms, and fish larvae; larger individuals feed on copepods, euphausiids, small pelagic fishes, young rockfishes, squid, and Octopoda (Ref. 6885). Oviparous, with planktonic eggs and larvae (Ref. 36610).
